This ticket includes changes for cell complexes and in general files in `src/sage/homology` for Python 3 compatibility. There are several types of changes:
- make sure data are sorted consistently,…
-
This patch adds more examples of simplicial complexes: real projective spaces (that is, RPd for any positive d), CP2, and the Poincare homology sphere. Some of these are the minimal triangulations,…
-
Sage now contains various lines of the form `from builtins import ...` which is provided by the `future` package.
Currently, `pyparsing` is needed for `src/sage/homology/simplicial_set_examples.py`…
-
It would be good to have a method to compute the automorphism group of a simplicial complex.
This patch implements that.
And also a procedure to check wether two simplicial complexes are isomorphi…
-
Add functionality so that we can compute a basis for (co)homology in dimension n of a chain complex C_* in terms of a given basis for C_n.
Apply: [attachment: trac_6100-basis_homology-ts.patch](htt…
-
Sage's CHomP interface is out of date: the executables now have different names and may use a different syntax. Also, CHomP has not been updated recently — the most recent changes at https://github.…

I haven't figured out when/why, but this might happen:
```
sage -t devel/sage/sage/homology/simplicial_complex.py

Sometimes a "bad exit 2" happens on Linux ppc64le due to this:
```c
/* src/saveload.c:127 */
libGAP_UInt1 libGAP_LOAD_BYTE_BUF( void )
{
libGAP_Int ret;
ret = read(libGAP_syBuf[libGAP_LoadFile]…
-
A lot of the stuff (not necessarily all) in `$SAGE_SRC/ext` belongs directly in the sage Python package--in particular any files that are needed for the package itself to function properly.
A mode…

This is preparation for #15585.
